We just got a 2 head semi auto keg washer. This particular keg washer has an inlet for compressed air which it uses to run the air valves, initial keg purge, initial post rinse water purge, caustic recovery, and post caustic rinse water purge.
We prefer to use acid rather than caustic in our keg washing process, and I don't like the idea of pumping compressed air into our kegs. Especially since I would have to purchase a larger compressor with enough capacity in addition to filters.
I've been using a nitrogen cylinder for the first few trial runs rather than compressed air and it's working pretty good, however, nitrogen is much more expensive than our bulk CO2 and this thing uses quite a bit of gas.
Is there any risk to using CO2 to run the air valves? I asked the "manufacturer" and their reply was that they have not tested it so they couldn't comment either way. I say "manufacturer" because I assume it was made in China as the manual lists all pressure specs in MPa and bar rather than psi and it's written in poorly translated Engrish.
Inlet pressure to air valves is 70psi.
